B) 3W

C) 1.4W

D) 20000W


show your work please

Answer 1

C) 1.4W

Step-by-step explanation:

Given;

energy of the battery, E = 10,000 J

duration of the battery, t = 2 hours

The power consumption of the battery is calculated as;

`Power = (Energy)/(time) \\\\Power = (10,000)/(2 * 3600 ) \\\\Power = 1.4 \ J/s = 1.4 \ W`

Therefore, the power consumption of the battery is 1.4 W
